RE: [LARTC] Some help please !

[Justin Owens <justin@commtech.ie>]

And when I do the following:
I try and send traffic on an un-specified port eg 25 and all the packets get
dropped; I though they would default into 1:12 and be allowed through ??

tc qdisc del dev eth1 root

tc qdisc add dev eth1 root handle 1: htb default 12

tc class add dev eth1 parent 1: classid 1:1 htb rate 600kbps ceil 600kbps
tc class add dev eth1 parent 1: classid 1:2 htb rate 900kbps ceil 900kbps
tc class add dev eth1 parent 1: classid 1:12 htb rate 12500kbps

tc filter add dev eth1 parent 1:0 protocol ip prio 1 u32 match ip dport 100
0xffff flowid 1:1
tc filter add dev eth1 parent 1:0 protocol ip prio 1 u32 match ip dport 150
0xffff flowid 1:2

As timer is acurate. And also remember I measure whole frames
with ethernet header. Depends what measures your meter.
For long lived traffic (several seconds) you can expect
about 1packet variation - it is 1% from rate for 100 packets.
